Answer:
Step-by-step explanation:
When he strated, he was at an elevation of - 55 m.
During the ride, the elevation changes as 412m,-125m,272m,-343m,490m,-640m and 50m.
Add up all the measures of the elevation of the rolar Coaster that are positive-55m+412m+272m+490m+50m=1279m
Now add up all the measures of the rolar costar that are negative-(-125m)+(-343m)+(-640m)= - 1108 m
Add up these two- 1279m+(-1108m)=
171m.
Hope that it helps.

Answer:
Elevation when he started =55m
Step-by-step explanation:
55+412+(-125)+272+(-343)+490+(-640)+50
467-125+272-343+490-640+50
342+272-343+490-640+50
614-343+490-640+50
271+490-640+50
761-640+50
121+50=171m
